Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current asset management systems for mobile workforces face challenges in accurately tracking high-value assets in real-time due to manual effort requirements, limitations of radio frequency solutions in metal environments, and difficulties in maintaining coverage outside vehicles.
Innovation Solution
A mobile asset tracking system using IEEE 1902.1 compliant tags and transceivers installed in vehicles to track assets within the vehicle and provide real-time location data, integrated with a centralized asset management system for improved visibility and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual paperwork inventories and bar code scanning are used to track high-value assets, then asset tracking capability is provided, but manual effort and time consumption increase significantly
Solution Approach 1:
The system employs automatic identification tags attached to assets that self-report their location and status to the centralized computer system without requiring manual scanning or paperwork completion by technicians. The tags continuously transmit data, enabling the system to automatically track asset movement and maintain inventory records.
Solution Approach 2:
The patent replaces manual mechanical processes (paperwork filling, bar code scanning) with electronic automatic identification and communication systems. Tags with transmitters automatically send asset data to the system, eliminating the need for manual intervention in asset tracking operations.
2Extent of automation
If radio frequency transceivers are used for asset tracking, then automated tracking is achieved, but coverage containment within vehicles becomes difficult and metal interference occurs
Solution Approach 1:
The system uses multiple transceivers positioned at different locations within the vehicle, each with localized coverage zones. This creates a network of overlapping local coverage areas that collectively provide comprehensive tracking capability while mitigating metal interference through spatial distribution of reading points.
Solution Approach 2:
The patent introduces intermediate communication relays and uses the vehicle's existing communication infrastructure as a mediator to transmit asset data from tags to the centralized system, overcoming direct RF limitations in metal environments by using multiple communication pathways.
3Loss of information
If comprehensive asset tracking is implemented across all locations, then real-time visibility is achieved, but system complexity and cost increase
Solution Approach 1:
The system uses universal tags that can track multiple types of assets (tools, equipment, vehicles, personnel) with a single standardized device. The centralized computer system serves multiple functions including asset tracking, inventory management, and location monitoring, reducing overall system complexity through consolidation.
Solution Approach 2:
The patent divides the tracking system into independent modular components: simple tags attached to assets, transceivers at fixed locations, and a centralized computer system. Each component performs a specific function and can be independently configured or replaced, reducing overall system complexity while maintaining comprehensive tracking capability.
